Cumulative pregnancy rates in infertile women with endometriosis.

We compared the effects of expectant and medical treatment on the fertility outcome in women with mild endometriosis. The five-year cumulative percentage of pregnancy with expectant treatment was 90%. In cases treated with 800 mg danazol a day for six months, the five-year cumulative percentage of pregnancy was 55.2. There was no statistical difference between the two groups. In surgically treated severe endometriosis the five-year cumulative percentage of pregnancy was 89.4. Patients with minimal or mild endometriosis should be offered expectant management for at least six months after all the associated factors are treated. Microsurgery is acceptable management for severe stages of the disease.
